Description

Technical Field

[0001] This application relates to the field of mechanical transmission equipment technology, and in particular to robot deceleration devices. Background Technology

[0002] Existing speed reduction devices are connected to the drive motor to reduce the rotational speed of the vehicle wheels. The speed reduction device contains bevel gears that mesh perpendicularly. The output shaft of the drive motor and the wheel axle are connected to these perpendicularly meshing bevel gears, so that the output speed of the drive motor is reduced by the speed reduction device before being transmitted to the wheels. Due to the internal component layout of the speed reduction device, its current form tends to be three-dimensional, resulting in the reduction gearbox of automobiles often being installed under the vehicle. For some vehicles used for off-road driving, the speed reduction device is installed too low. On uneven and potholed roads, the speed reduction device reduces the vehicle's obstacle avoidance ability and is prone to malfunctions during driving. Utility Model Content

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0024] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] refer to Figures 1 to 3 A preferred embodiment of the robot deceleration device according to this application will be described in detail below. The robot deceleration device is mounted on the vehicle frame to reduce rotational speed, increase torque, and improve the efficiency and stability of the mechanical transmission system. The robot deceleration device includes a mounting mechanism 10 and a deceleration mechanism 20.

[0027] The mounting mechanism 10 includes a mounting body 11. The deceleration mechanism 20 includes a driving component 21 and two driven components 22. The driving component 21 includes a drive member 211, which is rotatably mounted on the mounting body 11. The two driven components 22 are respectively assembled with axles connected to the two wheels. When the drive member 211 rotates, it can simultaneously drive the two driven components 22 to move synchronously, so as to drive the two wheels to rotate synchronously through the two axles respectively.

[0028] Each of the driven components 22 includes a reduction gear 221 and a transmission structure 222. The two reduction gears 221 are installed at intervals on the same side wall of the mounting body 11 and are both connected to the drive member 211. When the drive member 211 rotates, it drives the two reduction gears 221 to rotate synchronously.

[0029] Specifically, the belt drive 211, driven to rotate in a preset direction, causes both reduction gears 221 to rotate in the opposite direction to the rotation of the belt drive 211; that is, the two reduction gears 221 rotate in the same direction. When the belt drive 211 is driven to rotate clockwise, both reduction gears 221 rotate counterclockwise; when the belt drive 211 is driven to rotate counterclockwise, both reduction gears 221 rotate clockwise.

[0030] Preferably, the diameter of the reduction wheel 221 is larger than the diameter of the rotating component 211, so that the rotational speed of the reduction wheel 221 is lower than the rotational speed of the rotating component 211. The transmission structure 222 is driveably connected to the reduction wheel 221, and the transmission structure 222 included in each of the two driven components 22 is respectively connected to two axles, so that when the two reduction wheels 221 rotate, they respectively drive the two transmission structures 222 to move, so that the two transmission structures 222 drive the two wheels to rotate synchronously through the axles, thereby realizing that a single robot deceleration device synchronously drives the two wheels located on the same side of the frame and distributed front and rear to rotate synchronously.

[0031] Furthermore, the outer circumferential wall of the rotating component 211 is equidistantly formed with multiple first teeth, and the outer circumferential wall of the reduction wheel 221 is equidistantly formed with multiple second teeth, with the number of first teeth formed by the rotating component 211 being less than the number of second teeth formed by the reduction wheel 221. The first teeth and second teeth are engaged, and the rotating component 211 drives the reduction wheel 221 to rotate through the engagement of the first teeth and second teeth. In this way, the rotating component 211 and the two reduction wheels 221 are respectively distributed at different positions on the same side wall of the mounting body 11. Compared with the prior art, the robot deceleration device is more flattened, allowing it to be mounted on the flat side wall of the vehicle frame. Because the robot deceleration device is positioned higher, the vehicle's waterproofing and obstacle avoidance capabilities are improved, facilitating vehicle operation in the wild.

[0032] As an example, the belt drive 211 and the reduction gear 221 are both implemented as worm gears or gears.

[0033] refer to Figure 1 and Figure 2 Specifically, the mounting body 11 forms a first mounting sidewall 111 and a second mounting sidewall 112 opposite to the first mounting sidewall 111, wherein the belt rotating member 211 and the reduction wheel 221 are mounted on the first mounting sidewall 111.

[0034] refer to Figure 1 Furthermore, the mounting mechanism 10 also includes a protective component 12, which includes a first protective member 121. The first protective member 121 is mounted on the first mounting sidewall 111, and the first protective member 121 and the mounting body 11 together form an assembly space 101. The belt drive 211 and the reduction wheel 221 are located in the assembly space 101, and the lubricating oil adhering to the surfaces of the belt drive 211 and the reduction wheel 221 is confined within the assembly space 101.

[0035] Preferably, the mounting mechanism 10 further includes a cover assembly, which includes a first cover member that is fitted onto the first protective member 121 to cover the assembly space 101, thereby protecting the belt drive member 211 and the reduction wheel 221 and preventing the lubricating oil from being contaminated.

[0036] Preferably, an upper gap 22101 and a lower gap 22102, lower than the upper gap 22101, are formed between the two reduction wheels 221. The drive element 211 is located in the upper gap 22101 or the lower gap 22102 and is engaged with the two reduction wheels 221. The line connecting the axis of the drive element 211 and the axis of the two reduction wheels 221 forms a triangle, thereby shortening the distance between the two reduction wheels 221 on the side closer to each other, and thus shortening the distance between the two reduction wheels 221 on the side farther from each other. A larger space is reserved on the mounting body 11 of a preset size for subsequent assembly of the wheels in the vehicle's forward direction.

[0037] In one embodiment, the mounting body 11 is integrally formed with the vehicle frame, that is, the mounting body 11 is part of the vehicle frame, and the reduction mechanism 20 is directly mounted on the vehicle frame, thereby reducing the weight of the whole vehicle and reducing the manufacturing cost of the whole vehicle.

[0038] As deformable, the mounting body 11 is fixedly mounted to one side wall of the frame body by means of fasteners and / or welding, and the robot deceleration device is assembled into the frame body after being assembled, so as to facilitate the assembly of the various components included in the deceleration mechanism 20.

[0039] Furthermore, the driving component 21 further includes a driving structure 212, to which the rotating belt 211 is driven and connected, and the driving structure 212 is used to drive the rotating belt 211 to rotate. In a preferred embodiment, the driving structure 212 and the rotating belt 211 are located on the same side of the mounting body 11.

[0040] As an example, the drive structure 212 is implemented as a motor, and the output shaft of the motor is connected to the drive element 211.

[0041] refer to Figure 2 and Figure 3Preferably, the transmission structure 222 includes a first transmission assembly 2221. The first transmission assembly 2221 includes a first synchronous sprocket 22211, a first speed-reducing sprocket 22212, a first transmission chain 22213, and a first transmission shaft 22214. The first transmission shaft 22214 is rotatably mounted on the mounting body 11, and both the first synchronous sprocket 22211 and the speed-reducing sprocket 221 are mounted on the first transmission shaft 22214. The speed-reducing sprocket 22211 drives the first synchronous sprocket 22211 to rotate via the first transmission shaft 22214. The first speed-reducing sprocket 22212 is rotatably mounted on the mounting body 11, and the first transmission chain 22213 meshes with the first synchronous sprocket 22211 and the first speed-reducing sprocket 22212. When the first synchronous sprocket 22211 rotates, it drives the first speed-reducing sprocket 22212 to rotate via the first transmission chain 22213.

[0042] In the first embodiment, the first speed-reducing sprocket 22212 is connected to the axle, so that when the first speed-reducing sprocket 22212 rotates, it drives the wheel to rotate through the axle.

[0043] Preferably, the first speed-reducing sprocket 22212 has more teeth than the first synchronous sprocket 22211, and the diameter of the first speed-reducing sprocket 22212 is larger than the diameter of the first synchronous sprocket 22211. Therefore, the rotational speed of the first synchronous sprocket 22211 is greater than the rotational speed of the first speed-reducing sprocket 22212.

[0044] When the first speed reduction sprocket 22212 is connected to the axle, the rotational speed of the belt drive 211 is reduced twice by the speed reduction wheel 221 and the first transmission assembly 2221, thereby driving the wheel to rotate, so as to improve the speed reduction effect of the speed reduction mechanism 20.

[0045] Preferably, the protective assembly 12 further includes a second protective member 122, which is mounted on the mounting body 11, and the second protective member 122 and the mounting body 11 together form a receiving space 102, in which the first transmission chain 22213, the first synchronous sprocket 22211, and the first deceleration sprocket 22212 are all located. Lubricating oil adhering to the surfaces of the first transmission chain 22213, the first synchronous sprocket 22211, and the first deceleration sprocket 22212 is confined within the receiving space 102.

[0046] Preferably, the cover assembly includes a second cover member that is fitted onto the second protective member 122 to cover the receiving space 102, thereby protecting the first transmission chain 22213, the first synchronous sprocket 22211, and the first deceleration sprocket 22212, and preventing the lubricating oil from being contaminated.

[0047] Furthermore, the first transmission assembly 2221 further includes a first blocking member 22215, which is mounted on the mounting body 11 and located between the first synchronizing sprocket 22211 and the first decelerating sprocket 22212. The first transmission chain 22213 is wound around the outer periphery of the first blocking member 22215, thereby preventing the portion of the first transmission chain 22213 located between the first synchronizing sprocket 22211 and the first decelerating sprocket 22212 and remaining opposite to it from becoming entangled.

[0048] In one embodiment, the first transmission assembly 2221, the reduction wheel 221, and the wheel are located on the same side of the mounting body 11, and the second protective member 122 is mounted on the first mounting sidewall 111.

[0049] In another embodiment, the first drive shaft 22214 passes through the mounting body 11 and extends to both sides of the mounting body 11. One end of the first drive shaft 22214 is connected to the reduction gear 221, and the other end is connected to the first synchronous sprocket 22211. The first drive chain 22213, the first synchronous sprocket 22211, and the first deceleration sprocket 22212 are located on the second mounting sidewall 112 formed by the mounting body 11. In this embodiment, the second protective member 122 is mounted on the second mounting sidewall 112. In this way, the first drive chain 22213, the first synchronous sprocket 22211, and the first deceleration sprocket 22212 can be close to the second mounting sidewall 112, thereby reducing the size of the receiving space 102 perpendicular to the second mounting sidewall 112, so that a predetermined amount of grease can fully contact the first transmission assembly 2221 within the inner wall of the receiving space 102. In addition, the weight of the deceleration mechanism 20 is distributed on both sides of the mounting body 11, which can prevent the pressure on the mounting body 11 from being concentrated on one side, thereby preventing damage to the mounting body 11 and improving the stability of the mounting body 11.

[0050] refer to Figures 4 to 6In the second embodiment, the transmission structure 222 further includes a second transmission assembly 2222. The second transmission assembly 2222 includes a second synchronous sprocket 22221, a second speed-reducing sprocket 22222, a second transmission chain 22223, and a second transmission shaft 22224. The second transmission shaft 22224 is rotatably mounted on the mounting body 11, and both the second synchronous sprocket 22221 and the first speed-reducing sprocket 22212 are mounted on the second transmission shaft 22224. The first speed-reducing sprocket 22212 drives the second synchronous sprocket 22221 to rotate via the second transmission shaft 22224. The second transmission chain 22223 meshes with the second synchronous sprocket 22221 and the second speed-reducing sprocket 22222. When the second synchronous sprocket 22221 rotates, it drives the second speed-reducing sprocket 22222 to rotate via the second transmission chain 22223. The second speed-reducing sprocket 22222 has more teeth than the second synchronous sprocket 22221, and its diameter is larger than that of the second synchronous sprocket 22221, resulting in a higher rotational speed for the second synchronous sprocket 22221 than for the second speed-reducing sprocket 22222. The second speed-reducing sprocket 22222 is connected to the axle, so that its rotation drives the wheels to rotate synchronously via the axle. In this way, the rotational speed of the drive component 211 is reduced three times—by the reduction wheel 221, the first transmission assembly 2221, and the second transmission assembly 2222—before driving the wheels to rotate, further improving the speed reduction effect of the reduction mechanism 20.

[0051] Furthermore, the second transmission assembly 2222 also includes a second barrier 22225, which is mounted on the mounting body 11 and located between the second synchronizing sprocket 22221 and the second decelerating sprocket 22222. The second transmission chain 22223 is wound around the outer periphery of the second barrier 22225, thereby preventing the portion of the second transmission chain 22223 located between the second synchronizing sprocket 22221 and the second decelerating sprocket 22222, which remains opposite to the second barrier, from becoming entangled.

[0052] Preferably, the protective assembly 12 further includes a third protective member 123, which is mounted on the mounting body 11, and the third protective member 123 and the mounting body 11 together form a mounting space 103. The second transmission chain 22223, the second synchronous sprocket 22221, and the second deceleration sprocket 22222 are all located in the mounting space 103. Lubricating oil adhering to the surfaces of the second transmission chain 22223, the second synchronous sprocket 22221, and the second deceleration sprocket 22222 is confined within the mounting space 103.

[0053] Preferably, the cover assembly includes a third cover member that is fitted onto the third protective member 123 to cover the installation space 103, thereby protecting the second transmission chain 22223, the second synchronous sprocket 22221, and the second speed-reducing sprocket 22222, and preventing the lubricating oil from being contaminated.

[0054] In one embodiment, the second transmission chain 22223, the second synchronous sprocket 22221, and the second deceleration sprocket 22222 are arranged on the same side as the first transmission chain 22213, the first synchronous sprocket 22211, and the first deceleration sprocket 22212.

[0055] As deformable, the second drive shaft 22224 passes through the mounting body 11 and extends to both sides of the mounting body 11. One end of the second drive shaft 22224 is connected to the second synchronous sprocket 22221, and the other end is connected to the second deceleration sprocket 22222.

[0056] In a preferred embodiment, the second drive chain 22223, the second synchronous sprocket 22221, and the second deceleration sprocket 22222 are located on the first mounting sidewall 111 formed by the mounting body 11. In this embodiment, the third protective member 123 is mounted on the first mounting sidewall 111. This allows the second drive chain 22223, the second synchronous sprocket 22221, and the second deceleration sprocket 22222 to be close to the first mounting sidewall 111, thereby reducing the depth of the mounting space 103 perpendicular to the first mounting sidewall 111. A predetermined amount of grease, limited by the inner wall of the mounting space 103, can fully contact the second transmission assembly 2222.

[0057] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
